摘要

通过使用简单的过渡金属化合物（FeBr3）和 1,4-Cyclohexadiene (1,4-CHD) 作为供氢体，实现了烯烃的转移加氢。研究了多种二取代和三取代烯烃的转化，甚至还成功转化了一种四取代烯烃。与之前发表的使用更昂贵的 InBr3 的研究相比，反应时间大大缩短，反应条件也明显更温和。有趣的是，在 1,4-CHD 条件下，以分子氢作为化学还原剂，在 1 巴的压力下，也完成了催化转化。

The FeBr3-Catalyzed Transfer Hydrogenation of Styrene Derivatives under Mild Reaction Conditions

The transfer hydrogenation of alkenes was realized by using a simple transition-metal compound (FeBr3) and 1,4-cyclohexadiene (1,4-CHD) as the hydrogen donor. The conversion of a number of di- and trisubstituted alkenes was investigated, and even a tetrasubstituted alkene was successfully converted. Compared with previously published work with the more expensive InBr3, the reaction times were considerably reduced and significantly milder reaction conditions could be applied. Interestingly, a transformation that was catalytic in 1,4-CHD, with molecular hydrogen as a stoichiometric reducing agent at 1 bar, was also accomplished.
